Primary renal lymphoma is a rare tumor of the kidney that typically presents with bilateral nodular enlargement in the absence of extrarenal masses. We describe MR findings of a case of primary renal lymphoma along with ultrasound and CT findings. MR imaging demonstrated globular enlargement of both kidneys with multilobulated contour and multiple masses which had isosignal intensity on T1WI and low signal intensity on T2WI. The masses enhanced slightly on dynamic contrast enhanced scan.

Spontaneous pneumothorax is a known, but relatively rare complication of pulmonary metastases of sarcoma. A 19-year-old man was presented with chest pain and dyspnea for three days and was diagnosed as left pneumothorax. After bleb resection, microscopic examination revealed metastatic osteosarcoma forming subpleural fistula and dystrophic calcification. Four years ago, he had had limb salvage operation and chemotherapy for osteosarcoma of left femur. After two and a half years he had a bleb resection for right pneumothorax without any evidence of metastasis. Six months later, he was found to have a 4x3cm sized lung mass in the right lower lobe. After lobectomy, he was diagnosed as pulmonary metastasis of osteosarcoma. Pneumothorax is the common complication of metastatic osteosarcoma to the lung and it may be presented before the pulmonary metastasis is clinically evident. It is important to recognize a pneumothorax of the patients with osteosarcoma as a possible sign of metastases.

BACKGROUND/OBJECTIVES: The purpose of this study is to analyze daily kimchi, vegetable and fruit consumption by general characteristics and vegetable and fruit consumption from 1998 to 2012 by the Korean population based on the data of the KNHANES (Korea National Health and Nutrition Examination Survey). SUBJECTS/METHODS: This study is based on the 1998-2012 KNHNES. Analysis data on 54,700 subjects aged 19 years and older were obtained from health behavior interviews and the 24-hour dietary recall method. RESULTS: Daily kimchi consumption and portion size of kimchi decreased significantly from 1998 to 2012 (adjusted P for trend < 0.0001). Meanwhile, daily consumption of both non-salted vegetable and fruit with and without kimchi did not significantly change between 1998 and 2012. Reduced consumption of kimchi, non-salted vegetable, and fruit was observed for both genders as well as daily meal episodes and cooking locations. Male and female subjects with insufficient non-salted vegetable and fruit intake were increased 1.4 times and 1.3 times, respectively, in 2012 than 1998. All subjects consumed at least 400 g/day of non-salted vegetable, fruit, and kimchi in each survey year, although they consumed insufficient amounts (< 400 g/day) of non-salted vegetable and fruit without kimchi. CONCLUSIONS: Since Koreans generally consume high amounts of fermented vegetables, including kimchi, total vegetables and fruit. Consumption of these foods by the Korean adult population reached 400 g, which is the recommended intake of the WCRF/AICR. Based on this result, it is necessary to promote consumption of kimchi in the Korean population and research the development of low sodium kimchi in the future.

We identified Charcot-Marie-Tooth disease type 1A (CMT1A) in a family with schwannomas in the spinal cord and median nerve. The CMT1A in this family showed an autosomal dominant pattern, like other CMT patients with PMP22 duplication, and the family also indicated a possible genetic predisposition to schwannomas by 'mother-to-son' transmission. CMT1A is mainly caused by duplication of chromosome 17p11.2-p12 (PMP22 gene duplication). A schwannoma is a benign encapsulated tumor originating from a Schwann cell. A case of hereditary neuropathy with liability to pressure palsies (HNPP) concurrent with schwannoma has been previously reported. Although it seems that the co-occurrence of CMT1A and schwannomas in a family would be the result of independent events, we could not completely ignore the possibility that the coincidence of two diseases might be due to a shared genetic background.

PURPOSE: To evaluate whether soft tissue surrounding the celiac axis, as seen on abdominal CT imaging after gastrectomy for gastric carcinoma, should be considered as the recurrence of carcinoma or postoperative change. MATERIALS AND METHODS: One hundred and forty-one abdominal CT examinations of 71 patients who had undergone subtotal or total gastrectomy for gastric carcinoma were included in our study. Conventional CT scans were obtained with 1 cm thickness and interval from the diaphragm to the kidneys after contrast enhancement. It was considered that carcinoma had not recurred if findings were negative on UGI series, endoscopy with biopsy and a normal level of carcinoembryonic antigen except for soft tissue surrounding the celiac axis on abdominal CT. We then divided subjects into a recurrence group (N = 20) and normal group (N = 51) and on initial follow-up CT (FU-CT), analyzed the incidence, margin, shape, extent, degree and pattern of attenuation of the soft tissue surrounding the celiac axis in both groups. Since the second FU-CT examination, we observed changes in the soft tissue surrounding the celiac axis. RESULTS: On initial follow-up CT, at mean 308 days after surgery, fifty-five percent(39/71) of total patients (70% (14/20) of the recurrence group and 49% (25/51) of the normal group) showed soft tissue surrounding the celiac axis. The margin was distinct in 12 (86%) of the recurrence group and indistinct in 21 (84%) of the normal group (P < 0.001). Twelve (86%) of the recurrence group showed a nodular or confluent nodular shape and 21 (84%) of the normal group showed a permeative shape (P < 0.001). Extent was unilateral in eight (57%) of the recurrence group and bilateral in 16 (64%) of the normal group. Attenuation was similar to that of the spleen and muscle in seven (50%) of the recurrence group and was similar to that of muscle in 18 (72%) of the normal group. The pattern of attenuation was homogeneous in 13 (93%) of the recurrence group and 21 (84%) of the normal group. There was no significant difference in extent, degree and pattern of attenuation between the two groups. Since the second FU-CT examination, soft tissue surrounding the celiac axis was seen to have changed. In one patient in the recurrence group it had a distinct margin, was nodular in shape, unilateral in extent and showed attenuation similar to that of the spleen. In one patient in the normal group, it had changed and had an indistinct margin, three patients showed a decrease in the amount of soft tissue and eight showed decreased attenuation. CONCLUSION: Follow-up abdominal CT is useful in the differentiation of cancer recurrence and postoperative change, and for observing changes in soft tissue surrounding the celiac axis.

Pericardial defect is a rare congenital cardiac disorder. Most patients were asymptomatic but some patients with partial pericardial defect occasionally complain acute symptoms such as angina, syncope, rarely sudden cardiac death. So, differential diagnosis with other ischemic or structural heart disease is crucial in the management of such patients. But there is no consistently successful diagnostic method. In the past, artificial diagnostic pneumothorax was used to document the absence of pericardium. However, it is not easily accepted due to excess morbidity and failure rate. Recently, echocardiography and more often, computed tomography, magnetic resonance imaging are used to confirm the diagnosis. We experienced a 52 years old male patient with atypical chest pain, who was diagnosed as complete left pericardial defect with computed tomography.

PURPOSE: To investigate the differences in signal changes in the globus pallidus and white matter, as seen on T1-weighted MR brain images, and to determine whether these differences can be used as an indicator of subclinical hepatic encephalopathy. MATERIALS AND METHODS: A total of 25 cases of liver cirrhosis were evaluated.and as a control group, 20 subjects were also studied. Using a 1.5T MRI scannet, brain MR images were btained, and the differences in signal intensity in both the globus pallidus and thalamus and in both white and gray matter were then quantified using the contrast to noise ratio(CNR). On the basis of the Child-Pugh classification, 25 patients with liver cirrhosis were divided into three groups, with eight in group A, eight in B, and nine in C. Using clinical criteria, hepatic encephalopathywas diagnosed in seven of the 25 patients. Thereafter, CNRs(CNR1 and CNR2) were conpared between the control and cirrhotic groups and between cirrhotic groups with or without hepatic encephalopathy. RESULTS: In the control group, mean values were 3.2 +/-5.9 for CNR1 and 8.4 +/-8.0 for CNR2. In the cirrhotic group, these values were 10.6 +/-9.0 for CNR1 and 9.8 +/-6.4 for CNR2. A statistically significant difference was noted between normal and cirrhotic groups only for CNR1(p < 0.05). CNR values in patients with liver cirrhosis were 8.5 +/-11.5 for CNR1 and 11.7 +/-8.7 for CNR2 in the Child A group, 10.4 +/-5.1 for CNR1 and 9.3 +/-3 . 2 for CNR2 in the B group, and 12.8 +/-9.7 for CNR1 and 8.7 +/-6.5 for CNR2 in the C group. There was no significant difference in mean CNRI values between patients with or without hepatic encephalopathy. CONCLUSION: Differences in signal intensities in the globus pallidus and white matter, as seen on T1-weighted MR brain images, cannot be used as an indicator of hepatic encephalopathy in patients with liver cirrhosis.
